This spindle bearing is designed for precision high-speed applications, with a 25° contact angle and dimensions of 70.0 mm bore, 110.0 mm outside diameter, and 20.0 mm width. The net mass is 0.64 kg, and the limiting speed reaches 24000 1/min. The cage is designated T, and sealing is provided by non-contact lip seals on both sides (2RSD), matched to restricted tolerances for accurate positioning. The restricted tolerance class and non-contact sealing arrangement make this bearing suitable for mounting in pairs or sets under adjusted preload, supporting stable running at high rotational speeds while limiting friction and heat generation. The lip seals protect against contamination without adding contact drag, and the P4S accuracy class supports precise shaft guidance where minimal radial and axial deviation is required.
